The symptoms associated with a swollen foot include pain, edema, fatigue, inflammation, skin changes and fever according to WebMD and MedlinePlus. These symptoms are indicators of a wide variety of medical conditions such as sprains, fractures, congestive heart failure, blood clots, kidney diseases or lymphedema, reports WebMD.
Painless swollen feet occur in overweight or morbidly obese people or as a natural progression of aging, MedlinePlus reports. Swollen feet are usually indicators of underlying medical conditions and show symptoms such as puffy tissue under the skin, easily indented skin and changes in skin color, making the swollen areas paler then normal, notes MedicineNet. When accompanied by pain or tenderness in specific areas of the foot, swelling indicates the presence of an injury such as a fracture or a sprained ankle, according to Healthline.
Inflammation that accompanies swollen feet is an indicator of infections such as cellulitis, osteoarthritis or Achilles tendinitis, according to MedicineNet and Healthline. Cancer treatment can also cause lymphatic fluid to be trapped in the tissues of the foot, causing a swelling known as lymphedema, a condition that can prevent healing and cause infections, WebMD states. Moderate swelling of the feet and ankles is normal in pregnant women. However, rapid or abnormal swelling accompanied by high blood pressure and elevated protein levels are indicators of preeclampsia, a dangerous condition, explains WebMD.
